Mastering the Fix: How to Properly Use FastestLaps to Compare Cars (And Solve Display Glitches)
For decades, FastestLaps.com has been the unofficial data clearinghouse for petrolheads. Whether you want to know how a Tesla Model S Plaid fares against a Ferrari SF90 Stradale, or how a 1990s JDM hero stacks up against a modern hot hatch, FastestLaps offers one of the most comprehensive databases of lap times, acceleration data, and specifications.
However, veteran users often run into a frustrating issue: the "compare cars" feature sometimes breaks. Buttons don’t respond, graphs overlap, or the side-by-side layout looks "jammed" (hence the search for "fastestlaps compare cars fixed").
In this guide, we will break down exactly how to use the comparison tool correctly, how to fix the most common display bugs, and how to interpret the data like a pro.
The "Fixed" Logic You Need to Know
When the tool works correctly, it highlights three specific race scenarios: fastestlaps compare cars fixed
1. The Power/Weight Rule (Fixed Sorting)
The tool now automatically corrects for class disparities. If you compare a Porsche 911 GT3 (461 bhp/ton) against a BMW M4 (345 bhp/ton), the fixed algorithm clearly shows a 25% difference in red/green text—no manual math required.
2. Lap Time Sanity Check (Hockenheim Short)
The most stable metric in the fixed version is the Hockenheim Short lap time. Because the database normalized this specific track layout, you can finally trust that a 1:09.8 is actually faster than a 1:10.2 without worrying about weather-correction bugs.
3. The "Drag & Track" Discrepancy
Here is what the fixed comparison teaches you: Mastering the Fix: How to Properly Use FastestLaps
- Car A: 700 HP, 1,800 kg (Wins the quarter mile in the comparison chart).
- Car B: 500 HP, 1,200 kg (Wins the slalom and lap time).
The fix ensures that the lateral acceleration (g-force) stat doesn't accidentally swap columns.
1. Ambient Temperature is rarely fixed
A lap time set at 10°C (ideal for turbo cars) is not equal to a lap at 35°C (ideal for cooling). FastestLaps rarely stores this metadata.
Step 3: Fix the Source
The default view will show you every lap time from every source (Motortrend, Car and Driver, Top Gear, etc.).
- Action: Scroll down to the "Track Times" section.
- Filter: Check the boxes for only official manufacturer times or only a single publication (e.g., Sport Auto). By fixing the source, you fix the driving style.
Part 2: What Does "Fixed" Mean on FastestLaps?
FastestLaps isn't just a scraper of Wikipedia times. It is a database that attempts to normalize data through user submission and cross-referencing. When we talk about the "fixed" feature in the context of their comparison tool, we are referring to static parameter matching. Car A : 700 HP, 1,800 kg (Wins
Here is how the platform handles "fixed" comparisons:
3. Use the "Power-to-Weight" Graph
Below the lap table, you will see a simple scatter plot. It instantly reveals if a car is punching above its class. If a 400-hp car matches a 500-hp car around a track, that tells you everything about chassis engineering.
